# Cartes Bancaires

[Cartes Bancaires](https://www.checkout.com/payment-methods/cartes-bancaires) (CB) is the predominant card scheme in France. The majority of CB cards are co-branded with either Visa or Mastercard, meaning you can process these cards over either CB or the Visa or Mastercard schemes.

If a charge is declined for technical reasons on the CB scheme, we will automatically retry the charge on Visa's or Mastercard’s schemes. To opt out of this, contact your account manager.
